Yeah that's exactly how I do and I give to new sequence project a name with a digit always beginning by 0 so that explorer present me in the right increasing order
01 02 03 ....098 .In the name of the project to be saved I include the date written
like this 20150812 (yymmdd) again it enables a easy check in explorer.

Dave as a precaution before beginning the deletes first save the new project as a new one as it will automatically transfer you to the new one keeping the father project untouched. It so easy by mistake to forget to use save as instead of save in the process of the transfer.
